Fig. 4 and Table 5 show the mediated structural model results with the ˇ values of all path coefficients. Consistent with the unmediated model, social risk and delivery risk did not show any significant influence either in the direct or indirect path. We found that performance risk (ˇ = −0.273, t-statistic = 3.887, p < 0.01) and psychological risk (ˇ = −0.174, t-statistic = 2.114, p < 0.05) have a negative and significant impact on trust. Note that, after controlling trust, psychological risk still kept its direct impact on purchase intention (ˇ = −0.101, t-statistic = 1.836, p < 0.1); however, performance risk no longer showed a direct influence on purchase intention (ˇ = −0.038, t-statistic = 0.584, n.s.). Financial risk and online payment risk did not affect trust; yet, it only presented a direct impact on purchase intention (ˇ = −0.161, t-statistic = 2.384,p < 0.05 and ˇ = −0.154, t-statistic = 2.394, p < 0.01, respectively).Lastly, we found a significant positive impact of trust on purchase intention (ˇ = 0.428, t-statistic = 7.700, p < 0.01), which is necessary to support the hypotheses regarding the indirect impact of perceived risk on purchase intention by means of trust. R2 for purchase intention was 0.43, which is far greater than 0.291 found inthe unmediated model. In terms of R2, we found that R2 in creased greatly from 0.291 in the unmediated model to 0.428 in the mediated model, which implies that the mediated model has a better fit than the original model.
